Winter Tires

What type of technology do you use? Do you prefer an 8-track tape or an iPod? When it comes to winter tires, much of Sierra Vista driver's perception dates back to when 8-track was the best way to listen to the Bee Gees.

Twenty years ago in AZ, winter tires differed from highway tires only in their tread design. AZ drivers called them snow tires back then, and they had big, knobby lugs that were designed to give good traction in deep snow. They had the same rubber compound as regular tires and they weren't very good on ice, packed snow or wet AZ roads. They were not even very good on dry roads. They really helped in deep or loose snow, but they did a poor job the rest of the time. They were loud and rode hard. People couldn't wait to get them off in the spring.

Then all-season tires started to appear in Sierra Vista tire shops. All-season tires are really a compromise between summer and winter performance. They have acceptable hot weather ride and tread life and can get AZ drivers through mild winter road conditions OK. But there are some really good reasons to consider winter tires.

Modern winter tires do a terrific job for AZ driving in a wide range of winter conditions. First of all, below 45°F/7°C, regular tires become hard and inflexible. That means they don't provide the road grip AZ vehicles need. Even if you don't live somewhere in AZ with a lot of snow, but it still gets below 45°F/7°C in the winter, you will be safer with winter tires.

In addition, they are specifically designed to more effectively move snow and water. That's the key to traction on ice-packed snow and wet Sierra Vista area roads. They use a micropore compound that allows the tire to bite into ice and snow. They also use wider grooves that run around the circumference of the tread to expel snow from the tire better. The lugs and grooves on winter tires have a special shape that throws the packed snow out of the tread as the tire turns. The tread is then open when it comes back in contact with the road and can provide good traction for AZ drivers.

Winter tires also have a lot of sipes. Sipes are thin slits in the tread. The edge of the sipes grab ice and packed snow to provide tons of traction and to expel water and slush out of the tread. Winter tires have a rounder casing to cut into the snow's surface. The treads on regular summer tires can actually get packed with snow instead and become very slick. Winter tires offer 25% to 50% more traction for AZ drivers than all-season tires. And when it comes to stopping power, all-season tires take 42% longer to stop than winter tires. Sometimes that's the difference between getting home safely and spending the night in a snow bank.

Now back when the 8-track was king, AZ drivers just put snow tires on the drive wheels. That worked out OK because the rubber compound was essentially the same. Now, winter tires provide so much more traction than all-season or summer tires, that there's a huge difference between the traction at the front and rear ends of the car if you only put winter tires on the drive wheels.

For example: if you take a corner on an icy road and the rear end starts to slide out, essentially the rear is trying to pass the front because it's going faster. If you have high traction winter tires only on the front, they are going to be much more effective at transferring cornering grip and stopping power to the front wheels. This will actually cause the rear end to whip out even more.

That's why tire manufactures instruct their dealers that they must install winter tires on the rear wheels as well whenever they put winter tires on the front end of any vehicle. It's a major safety concern. It's strongly recommended that winter tires be installed on all four wheels on rear wheel drive vehicles as well. The front tires do most of the steering and braking work - it only makes sense that you provide the front end with the best traction you can.

Sierra Vista drivers often assume that if they have four-wheel drive or all-wheel drive they don't need winter tires on all four wheels. Would you intentionally disconnect the four-wheel drive in poor road conditions? Of course you wouldn't, but that's essentially what you do if you only put winter tires on one end. It only makes sense to have the same level of traction and control at all four corners.

The province of Quebec in Canada has issued a law requiring all passenger vehicles, taxis and rental cars with Quebec license plates to install a full set of four winter tires between November 15th and April 1. It's that important.

Many modern cars have traction control and anti-lock brakes so AZ drivers may think that they don't need winter tires. But you need traction to accelerate, steer and stop. The tires provide the traction so that the traction control and anti-lock brakes have something to work with.

Look for tires with the symbol of a mountain with a snowflake in it. This means the tire complies with the severe snow standard. All-season tires will have an M&S, for mud and snow, on the sidewall.

So when the Sierra Vista temperatures drop below 45°F/7°C, be sure you have a set of four winter tires for maximum performance on snow, packed snow, ice, plus wet and dry roads. Your friendly and knowledgeable Arizona Auto and Radiator Repair tire professional can help you find the right winter tire for your vehicle and driving needs.

Severe Service Requirements

A lot of Sierra Vista drivers have asked whether or not they should use their severe service maintenance schedule, which is listed in their vehicle's  owner's  manual. It can be somewhat confusing, so we decided to consult an expert. Cricket Killingsworth is from QMI/Heartland, a manufacturer of automotive products and fluids. She's been in the automotive business for over 30 years and is a speaker, a trainer and a writer.

Cricket says there's so much confusion on this topic because, "Most owner's manuals actually have two maintenance schedules. Sometimes these are called 'regular service' and 'severe service.' Sometimes they're simply called Schedule 1 and Schedule 2. A severe service schedule recommends that things like an oil change, air filter replacement and transmission service be done more often: either in fewer miles or in less time."

Foreign and domestic vehicle manufacturers create a specific schedule for each vehicle they manufacture. So there isn't one generic schedule that applies to all vehicles. In addition to your owner's manual, Sierra Vista automotive repair centers (including Arizona Auto and Radiator Repair) subscribe to information services that provide the auto maintenance schedules for every vehicle - so they can help Sierra Vista drivers know when to take care of needed services. Below is a typical definition for severe service.

• Most trips are less than four miles/six and a half kilometers
• Most trips are less than 10 miles/16 km and outside temperatures are below freezing
• You drive regularly in very hot AZ weather
• The engine is at low speed most of the time (not on the freeway)
• Stop and go driving
• You drive in in dusty or muddy conditions
• You routinely tow a trailer, haul heavy loads or carry a car-top carrier around Sierra Vista

It's common sense for Sierra Vista drivers: Just a few minutes at higher speeds allows the moisture in the oil to evaporate. Very short trips, or trips of less than 10 miles when it's very cold, don't allow the engine to heat up enough to get rid of the water. And water in the oil leads to damaging sludge. Also, towing and heavy loads raise operating temperatures and cause fluids to break down faster. Dusty and muddy driving around Sierra Vista means that more dirt will get past the air filter to contaminate the fuel system and engine oil.

The bottom line is that you need to decide for yourself if the regular or severe service schedule is right for you, based on your driving habits. Look at your owner's manual or talk with your Arizona Auto and Radiator Repair service advisor who can help you know which schedule to follow.

Here is what a fleet manager said recently: "Since city miles are generally tougher on vehicles than highway miles, we use the manufacturer's severe service schedule as the basis for our preventative maintenance program. We massage those schedules over time, increasing or decreasing the service intervals so that they make the most sense. There is a little bit of art to go along with the science."

Make an honest evaluation of your driving habits. Unless you do mostly AZ highway driving in moderate weather, you'll likely have a fairly good amount of severe service mixed in. Some Sierra Vista drivers just want to play it safe and follow the severe service recommendations, rather than analyzing how they drive each month.

Ask us for help evaluating your driving and service needs.

Fuel Injectors

The last new American vehicles sold in Sierra Vista with a carburetor rolled out of the AZ dealerships in 1990. Since then, all new vehicles here in Sierra Vista, and nationally, have had fuel injectors. In very simple terms, a fuel injector is a valve that squirts fuel into your engine. Your engine control computer tells the fuel injector how much gas to deliver as well as the precise time it should be delivered. Of course this happens thousands of times a minute. Fuel injectors deliver fuel far more precisely than carburetors. That translates into better fuel economy and more power for Sierra Vista drivers. Virtually all fuel injectors for gas engines are known as port fuel injectors because they deliver the fuel to a port just outside the cylinder. Port fuel injectors operate at about 40 to 80 pounds per square inch of pressure.

A few vehicle manufacturers have introduced gas direct injection systems on some engines recently. These systems inject the gas directly into the cylinders under very high pressure - hundreds of times the pressure of port injection systems. Although more complicated, direct injection technology promises greater power with improved fuel economy, so AZ drivers can expect to see more of it in the future.

As Sierra Vista residents can see, the level of precision required of fuel injectors is very high. It's important that they operate properly in order for your vehicle to run right.

High temperatures under your hood and variations in Sierra Vista gas quality cause fuel injectors to become fouled with wax, dirt and carbon. Injectors can become partially clogged, preventing them from delivering the proper amount of fuel at the correct pressure. The design of each engine requires a specific spray pattern from the fuel injector that might be altered when the injector is dirty. When injectors are dirty, the fuel doesn't burn as efficiently, resulting in poor fuel economy and loss of power. So it is important to keep your vehicle fuel injectors clean.

Skilled service technicians at Arizona Auto and Radiator Repair in Sierra Vista can perform a fuel system service for you. That is a fuel system service - not just fuel injector cleaning. That is because the fuel has a lot of ways to become dirty or contaminated between the Sierra Vista gas pump and your fuel injectors. A fuel system service at Arizona Auto and Radiator Repair starts with a fuel filter replacement. This filter cleans the gas as it leaves the tank. The various parts of the fuel intake system need to be cleaned from time to time to remove harmful gum deposits and varnish. Finally, the fuel injectors are cleaned so that they operate properly for you and deliver the right amount of fuel at the right time.

Our pros at Arizona Auto and Radiator Repair use a process for cleaning your vehicle fuel system that includes state-of-the-art cleaning chemicals as well as some old fashioned scrubbing. Proper maintenance of your fuel system means that you will enjoy strong performance and prevent repairs down the road.

Exhaust Service at Arizona Auto and Radiator Repair in Sierra Vista

Whenever they hear the term "exhaust service," most Sierra Vista residents think about exhaust pipes and mufflers. Well, actually, exhaust service at Arizona Auto and Radiator Repair is a lot more comprehensive these days. For example, catalytic converters were mandated in 1976 and on-board emission control computers in 1990. Governmental emissions requirements have forced manufacturers to come up with much more sophisticated ways to comply with environmental regulations.

Exhaust service has really become exhaust and emissions service. High-tech computer controlled emissions devices are now a big part of exhaust service. Because it is so sophisticated, your recommends you have your emission system checked out by a qualified Sierra Vista exhaust technician regularly to make sure everything is working right - usually every 6 months or 10,000 miles/16,000 kilometers.

If your Check Engine light comes on, especially if it's flashing, get your car looked at right away. Technicians at Arizona Auto and Radiator Repair in Sierra Vista handle emission problems everyday. You might have exhaust or emissions trouble if your car is difficult to start, runs rough, is noisy or smoking. Call Arizona Auto and Radiator Repair at 520-459-2216 to schedule an appointment if you experience these problems.

Let's review the exhaust system. We will start from the top with the exhaust manifold. That is the part that attaches to the engine and collects the exhaust from the cylinders and directs it into the exhaust pipe. Exhaust gaskets help seal the connection with the manifold and various other joints along the way. If the manifold is cracked or loose or a gasket is leaking, gases could escape into the passenger compartment where you ride. Carbon monoxide can be deadly, so it is important that your exhaust system doesn't leak. The exhaust pipes connect the various components. They can rust or be damaged by a rock, so they need to be inspected periodically.

Next is the catalytic converter. This part looks like a muffler. It changes chemicals that are dangerous to your health and our Sierra Vista environment into harmless carbon dioxide and water. It doesn't require any maintenance itself. But eventually they wear out. Sierra Vista drivers find this out when their car fails an emissions inspection.

Now the muffler. Its main job is to quiet engine noises. Mufflers work by either absorbing or baffling sound. And you can actually customize your car's sound with different mufflers - anything from whisper quiet to bad-boy rumbley. Rusted or road-damaged mufflers can leak and need to be replaced right away. Talk to your friendly and knowledgeable service advisor at Arizona Auto and Radiator Repair .

The exhaust system is attached to the vehicle by a series of hangers and clamps. These fasteners hold the system in place. When hangers come loose or break, hot exhaust components can touch and melt wires, hoses and lines.

Finally, we end at the tailpipe. This is the final outlet for the exhaust. These can be plain-Jane or pretty flashy. Also, the oxygen sensors monitor the oxygen content of the exhaust so the engine control computer can adjust the fuel-to-air mix to keep the car running right.

Exhaust and emissions service at Arizona Auto and Radiator Repair in Sierra Vista covers plain old pipes and high-tech computers. It impacts everything from life-and-death safety due to exhaust leaks to fine-tuning the sound of your ride.

Differential Service

When you take a corner in your car, the outside wheels have a slightly longer distance to go than the inside wheels.  That means that the outside wheels must turn a bit faster than the inside.  The piece of mechanical wizardry that makes this possible is called the differential.

The differential allows the drive wheels to rotate at different speeds in turns without the wheels binding or hopping.  If you have a rear-wheel drive vehicle, the differential is on the rear axle.  You’ve seen that bulge in the middle of the axle when you’re behind a truck – that’s the differential.

If you have a front-wheel drive vehicle, the differential function is handled by your transaxle.  Of course, all-wheel drive vehicles have differentials on both axles.  They also have a center differential or a transfer case between the front and rear axles to compensate for speed differences between the front and rear.

Because all the power of the engine is transferred through the various differentials, you can imagine that they are very strong and are built last a long time.  That’s why it’s important to keep your differential properly lubricated.  Differential fluid cools and protects the gears.

Your service technician will check differential fluid level and top it off if necessary.  With low fluid, the differential will run too hot and wear prematurely.  Ask your service advisor for when it’s recommended to change your differential fluid.  Fresh fluid will extend the life of your differential.  Your technician will also inspect the u-joints which connect your drive shaft to the differential and may recommend service.  Some u-joints can be lubricated as part of a routine lube, oil and filter change as well.

Now, of course differentials eventually wear out and need to be replaced.  You might notice a strange noise from your axle area as one of the first warning signs.  When the differential shows signs of failing, it’s important to repair it.  If you leave it too long and it freezes up when you’re driving you could lose control of your vehicle and other parts like the axle, driveshaft and transmission could be damaged.

Cabin Air Filter From Arizona Auto and Radiator Repair

Here is a questions for Sierra Vista drivers: What is a cabin air filter?

Is it:

1. A filter for a house in the middle of the woods?
2. A fresh, piney scent?
3. A filter for the passenger compartment of your car?

Clever you, it's 3.

A cabin air filter cleans the outside air before it comes into the passenger compartment. It filters out dust, pollen, spores, bacteria, pollutants, sparrows, exhaust gas and odors.

These high tech filters can block particles larger than 3 microns. By contrast, a grain of sand is about 200 microns.

Now not all vehicles in the Sierra Vista area have cabin filters. They are fairly new on the scene in AZ. About 40 percent of new vehicles come with cabin air filters, but the number is growing every year.

Cabin air filters can make for a very nice driving environment for Sierra Vista. Your car can be a haven during AZ allergy season with very little dust and pollen getting into the cabin. However, like all filters, your cabin air filter eventually gets clogged. When this happens, your heating and air conditioning flow can become restricted. The filter can even get kind of smelly.

Check your vehicle's owner's manual for recommended replacement intervals. Often, the owner's manual forgets about the cabin air filter, so ask your friendly and knowledgeable Arizona Auto and Radiator Repair service advisor for a recommendation. It's usually every year or 12,000 miles/19,000 kilometers. Change it sooner if you drive in dusty Sierra Vista conditions or if you start to notice an odor from your ventilation system.

So, Sierra Vista drivers, keep your cabin air filter clean. It may not help with your brother-in-law in the backseat, but it will make your driving experience more enjoyable.

Power Steering Service Near Hereford

For most of us living in the Hereford area, it is hard to remember life without power steering - cranking those great big steering wheels? It was a pretty good workout. Now power steering is standard. The heart of any power steering system is its pump. The pump pressurizes the power steering fluid that provides assist for steering. Most pumps are driven by a belt that is run by the engine - a few are electrically powered. A high-pressure hose passes fluid from the pump to the steering gear. A low pressure hose returns the fluid back to the pump.

These hoses can develop leaks, so it is a good idea to inspect them at every oil change. Low fluid can damage the power steering pump. That is why fluid level is on the checklist for a full-service oil change. The fluid needs to be compatible with the hoses and seals, so check your owners' manual for the right type - or just ask your service technician at Arizona Auto & Radiator Repair.

The fluid cleans, cools and lubricates the power steering system. It breaks down as the years go by and collects unwanted moisture, so it needs to be replaced from time to time. Many manufacturers specify power steering service intervals. Unfortunately, this important service is sometimes left off the maintenance schedule for many of us in Hereford. So, when in doubt, every 25,000 miles/40,000 km or two years is a good fallback. Your Arizona Auto & Radiator Repair service center in Hereford will use a detergent to clean the system, flush out the old fluid and replace it with the good stuff.

Here are some warning signs of trouble with your power steering: It's harder to turn the wheel, there's erratic power assist, you hear loud whining coming from the pump (which may be difficult to hear over the loud whining coming from the backseat), you have to top-off the fluid frequently, or you hear squealing belts. Remember to never hold the steering wheel to the far right or left for more than a few seconds at a time. That will wear out your power steering pump real fast.

Other steering components can be bent or damaged from wear or hard knocks. Ball-joint, idler-arm, steering-gear, steering-knuckle and tie rod to name a few. Warning signs here are steering play, wandering, uneven tire wear, and off-center steering wheel. An annual alignment check at Arizona Auto & Radiator Repair will reveal bent or damaged steering components.

Most SUV's, pick-ups and rear-wheel-drive cars need regular front-wheel-bearing service.

The bearings should be cleaned and inspected. If they are excessively worn, they need to be replaced. The bearings are then repacked in clean grease. It's also recommend the wheel-seal be replaced when the bearings are serviced. Like everything else, check your owners' manual maintenance schedule. It's usually required around every two years or 40,000 miles/64,000 km. If you drive through water in the Hereford area, the bearings will need service more often.

Proper Fluids for Your Vehicle

We would like to give you an update on some of the things happening in automotive fluids. You know, cars are becoming more sophisticated everyday - and fluids such as, oil, coolant and transmission fluid are becoming more specialized at about the same pace.

The do-it-yourselfer has to be pretty careful so that they do not actually harm their vehicle with the wrong type of fluid. That is why so many AZ car owners rely on the advice of their service consultant to not only get the correct family of fluids, but to suggest the formulation that is best for their car and the way they drive.

Let's start with engine oil. If you have been paying attention, you will have noticed a number of new oil weights on the scene in the last several years. Modern engines are built to much tighter tolerances and have very complicated valve trains. The oil must be thin enough to lubricate complicated parts when the engine is cold. The weight of an oil is expressed in terms like 20-W-50 or 5-W-30. Manufacturers recommend the weight of oil for each vehicle they make. The recommendation is based on engine design. Your Sierra Vista service center will know what weight your manufacturer recommends - and it's important to follow those recommendations. A service adviser at Arizona Auto & Radiator Repair can also offer suggestions for special formulations and can explain conventional and synthetic oils.

Antifreeze, or engine coolant, is another area that has become more complicated. For a long time, manufacturers only called for a couple of different types of coolant. Now there are several different formulations that are needed because of the different materials that manufacturers are using to build the cooling system. Using the wrong type of coolant can actually void your warranty, so you want to get that right.

Transmission fluid is beginning to be specialized as well. New transmission designs have particular requirements that mandate the use of specific formulations. Recently, new, somewhat confusing, standards for brake fluid have also been released.

Not too long ago, there was a good chance that all of the vehicles at your house would use many of the same fluids. However, as automotive technology advances, the array of basic automotive fluids you need will grow. And, some of the formulations will cost a little more. Fortunately, your Hereford service center will continue to update their training to keep pace with technology so that you'll get the right fluids your car needs. It's all part of the commitment your service center makes to your driving peace of mind.

Arizona Auto and Radiator Repair Radiator Service

The coolant system is a vital part of your vehicle. It is also the second most common cause for vehicle failures. Even though coolant system failure is fairly common in Sierra Vista, it is easy to prevent.

The most recognizable part of the coolant system is the radiator. It is connected to the engine with hoses and is filled with coolant. The coolant draws heat off the engine and then passes into the radiator. Air passes through cooling fins to reduce the temperature of the coolant and then it's back to the engine again.

There are several ways for the cooling system to fail. Most common is with the coolant itself. Coolant is comprised of water and antifreeze. The proper ratio keeps the coolant from either boiling away or freezing. Understandably, either can lead to massive engine damage.

Another coolant issue that is often overlooked by Sierra Vista drivers is the age of the coolant itself. Antifreeze has additives that protect the coolant system from corrosion. As these additives are depleted over time, they can't protect the radiator and other parts from rust, scaling and corrosion. That old container of coolant gathering dust in your garage may still keep your engine cool, but it won't protect it from corrosion.

If you get a warning message to check the coolant or if the vehicle temperature gauge is in the hot zone, your cooling system needs to be checked. It's OK to add water or antifreeze yourself. But you need to be cautious. Remember four things:

• First, you never want to open the radiator pressure cap. You could be severely burned.
• Second, get to Arizona Auto and Radiator Repair in Sierra Vista immediately if your coolant is low. If that is not possible, follow the directions in your vehicle owners manual - it will direct you to only make additions to the coolant overflow bottle.
• Third, remember that you need a proper mixture of water and antifreeze. If you make an emergency addition to your cooling system, follow-up with your Arizona Auto and Radiator Repair service center where we can make necessary adjustments.
• Fourth, not all cars use the same type of antifreeze. You need to check your vehicle owners manual to make sure you use the right kind. Mixing antifreeze types or using the wrong kind of antifreeze may void the manufacturers warranty on your cooling system. Again, another reason to depend on your Arizona Auto and Radiator Repair service center in Sierra Vista to do things right.

Remember, Arizona Auto and Radiator Repair has the equipment to change your coolant quickly and inexpensively.

Suspension Service in Sierra Vista at Arizona Auto and Radiator Repair

When they hear the word suspension, many drivers in Sierra Vista may think back to those energetic days of grade school. Well, your vehicle's suspension is actually a good thing because it keeps your vehicle up off the road and helps provide a comfy ride around Sierra Vista. Its job is to keep your wheels firmly planted over bumps and through curves. Your suspension system has many parts. If you look under your vehicle, it's basically everything that connects your wheels to the vehicle's frame. These are heavy duty parts that do a lot of work. They need to be inspected for damage and excessive wear at least once a year. A good time for this is when you get your annual alignment service at Arizona Auto and Radiator Repair.

Here are some warning signs of suspension problems:

• the car pulls to one side
• it wanders
• the steering is erratic
• you see uneven tire wear
• you experience a poor ride or handling
• you see oil leaking from shocks

Basically, you just don't feel in control when you're driving.

Some suspension parts just wear out with use. Shocks and struts eventually lose their ability to control your ride. Wheel bearings need to be repacked every couple of years. And some suspension pieces need to be lubricated when you get your oil changed. Your service advisor at Arizona Auto and Radiator Repair can perform an inspection and tell you what problems you may have.

If you're in an accident, your suspension can be damaged or knocked out of alignment. Even a minor accident, like hitting a curb around Sierra Vista or even a large rock can mess things up for drivers. With a minor accident it's tempting for many to just get an alignment or wheel balance to correct the problem. But if there's damage, a simple alignment won't actually fix the problem, and you'll just have to align it again after the repairs are made. So if you have an accident, get your suspension system inspected right away. Suspension problems are a major safety issue because they can lead to unsafe handling.

One big cause of suspension damage for Sierra Vista drivers is potholes – those nasty magnets that form in roads in freezing weather. They seem to draw our tires right into them. Here are some tips for avoiding damage from potholes: First, keep your tires at their full air pressure. That gives tires their maximum resiliency and will hopefully keep your wheels or other suspension parts from crunching on a big hole. Next, just pay attention. When you see a hole you can't miss, slow down before you hit it. Driving at a slower speed will limit the damage and may keep your drink from spilling. But avoid the temptation to brake directly over the pothole. That will cause the car's weight to shift forward and add to the potential damage.

Trip Inspection at Arizona Auto and Radiator Repair in Sierra Vista

Sierra Vista area drivers love their vehicles. And one of the most enjoyable things about them is taking a road trip. Freedom from daily schedules, new sights and the open road – it's great! But there's nothing like vehicle trouble to bring the fun to a grinding halt.

Now Sierra Vista drivers can't always avoid problems, but you can take steps to reduce the probability of getting sidelined on your trip. The first step is to look at your trip plan from your vehicle's perspective. What kind of roads will you be traveling – winding AZ byways? Purple mountain majesties or fruited plains? What weather conditions are you likely to encounter? How far will you travel each day? How much weight will you be hauling – passengers and luggage? Pulling a trailer, roof top carrier or ATVs? Will it be dusty?

Prepared with answers to these questions, you can schedule a trip inspection at Arizona Auto and Radiator Repair in Sierra Vista to help you prepare your vehicle for your big adventure. A lot of our Sierra Vista customers prefer to go through this exercise with their friendly and knowledgeable service advisor to get their input and make sure they haven't overlooked anything.

A great place for Sierra Vista drivers to start is with the tires. Inspect them for tread wear and proper inflation. Is it time to rotate your tires? Replace them? Are they up to the job? You wouldn't want to drive regular highway tires on a muddy off-road adventure on AZ rock-crawling trails. 

Shocks and struts play a major role in both driving comfort and safety. If they need to be replaced, you'll really be glad you did once you hit the road. Is it time for a wheel alignment? Fighting a car that's pulling to one side all day can be tiring and dangerous. 

And don't forget your brakes. Any strange noises, grabbing, soft or hard peddle feel? If there is any doubt, get a brake inspection at Arizona Auto and Radiator Repair in Sierra Vista before you leave.

Moving under the hood, have a belts and hoses inspection. If something is excessively worn or near failure, the stress of a long road trip might just be the straw that breaks the camel's back. Talk to your service advisor at Arizona Auto and Radiator Repair.

Your engine air filter will be inspected. Your car's air filter will process 12,000 times as much air as the fuel burned by the engine. If the filter needs to be changed, you'll notice improvements on your trip.

How close are you to your next oil change? Will you be able to complete your trip before it's due? If not, just get it taken care of before you go so that you don't need to interrupt your trip. In fact, a full service oil change at Arizona Auto and Radiator Repair is a great idea because they will top off all your fluids and check to see if any other maintenance items are due, such as transmission or cooling system service.

Do you notice any unusual odors in your vehicle? If so, it could be as harmless as a dirty cabin air filter. But if it's an exhaust leak, it could be fatal for Sierra Vista drivers and their passengers on a long trip. Of course you'll want to be comfortable, so get an air conditioning service if you aren't getting the cold air you’re used to. 

Are your wiper blades still working well? If not, that is a quick and inexpensive fix for Sierra Vista drivers. Headlamps are often overlooked when planning for a trip. If you haven't changed the bulb in six months or so, replacement bulbs will really light up the night on your trip and provide the necessary after-sundown visibility.

All the items mentioned are part of any good vehicle maintenance plan. These are things that you want to take care of anyway, but they all become more important as you plan for your trip.

They will always save you money in the long run and may prevent inconvenient stops and delays on your trip. After all, you wouldn't want to miss the world's largest ball of string, would you?

Braking News: Keep Your Stopping Power

Richard Petty once told AutoNetTV, “You've gotta have good brakes. If you've got good brakes you can keep yourself out of a lotta trouble.”

That's why a regular brake inspection is on every Sierra Vista driver's maintenance schedule. An inspection by your service advisor at Arizona Auto and Radiator Repair will check your brake system and let you know if there are any problems.

Of course, if you're having trouble with your brakes, get your car into Arizona Auto and Radiator Repair in Sierra Vista right away. Here are some symptoms for Sierra Vista drivers to watch for:

• Low or spongy brake pedal
• Hard brake pedal
• A brake warning light that stays on
• Constantly squealing or grinding brakes
• Vibrations or clunking sounds when you apply your brakes

If you are experiencing any of these, it's time to get your brakes checked. Talk to your friendly and knowledgeable service advisor at Arizona Auto and Radiator Repair .

There are two types of brakes: disc and drum. Disc brakes have a rotor that's attached to the axle. Calipers straddle the rotor, kind of like the brakes on a bicycle.

Drum brakes are most common on back wheels. Both types have pads or shoes that press against the brakes and slow the vehicle. Brake pads and shoes are made out of very tough material to withstand the heat and force generated when stopping your vehicle. Eventually, they wear out with use and become too thin and need to be replaced at Arizona Auto and Radiator Repair. 

If the brake pads wear away completely, you can damage the rotors. The calipers can grind grooves in the rotor. Then the rotor must either be resurfaced or replaced. That's not only expensive but also dangerous because your vehicle won't stop as quickly. Sometimes rotors warp or crack and must be replaced.

A brake service at Arizona Auto and Radiator Repair will also include a check of your brake fluid. When the brakes are applied, the pressure in the fluid activates the brake pads or shoes. Not enough fluid means not enough pressure to brake properly. Also, water builds up in the brake fluid over time, which leads to corrosion, leaks and brake damage, and with hard use, the brakes could severely fade or even fail. Sierra Vista  drivers should change the brake fluid when their  vehicle manufacturer recommends to avoid these problems.

Come in to Arizona Auto and Radiator Repair for an brake inspection before damage occurs. You can call ahead for an appointment by calling 520-459-2216.

What to Do After You Buy a Used Vehicle in Sierra Vista

So you've bought a used vehicle in the Sierra Vista area. Do you know what you're getting? It is hard to know what you're getting because people in the Sierra Vista area sell vehicles for different reasons. Think about why you've sold vehicles. Did you just want something new or were there problems that you wanted to run away from? Maybe it was a little of both.

Used vehicles in AZ with 25,000 to 35,000 miles/40,000 to 55,000 km on them are often lease returns, corporate program cars or rental fleet vehicles. Most Sierra Vista buyers feel pretty confident about these because they're newer and may still be under warranty. But how well have they been maintained?

Sierra Vista drivers who are planning to own a vehicle for a long time will keep up on auto maintenance so that they can avoid repairs down the road. But, if you know you're only going to have the vehicle for two or three years, you may not be so committed to maintenance. It would be easy to think that skipping an oil change here and there wouldn't ruin a brand new engine. Then it'll be someone else's problem when it comes time to pay for the damage.

It is very tempting for Sierra Vista drivers to skip the 30,000 mile/50,000 km service if they know they'll be turning in their leased vehicle in a couple of months.

If the vehicle didn't come with maintenance records, Sierra Vista used vehicle buyers need to assume the worst. Most likely the coolant system and transmission have never been serviced. The cabin air filter has probably not been changed and a fuel system cleaning at Arizona Auto and Radiator Repair may be in order.

You'll want Arizona Auto and Radiator Repair to check the A/C, battery, engine air filter, serpentine belt and hoses. A used vehicle inspection at Arizona Auto and Radiator Repair is well worth the cost.

And if your “new” used vehicle has been driven an even longer distance, an inspection is even more important. Check your owner's manual or talk with your service advisor at Arizona Auto and Radiator Repair about what should have been done. Please don't forget the timing belt; that can be very expensive if it fails.

Arizona Auto and Radiator Repair will help you with a plan to take care of services and get the rest caught up. If your budget won't allow you to take care of everything right away, we can help you prioritize your needs and get it taken care of over the next several months. And remember to keep your maintenance records. They'll help you get top dollar on the AZ used vehicle market when it's time for you to sell.

Keep Your Cool in Sierra Vista

Sierra Vista drivers rely on their vehicle's coolant system to keep their engine cool. Coolant (also called antifreeze) mixed with water flows through your vehicle engine and absorbs heat. The mixture then flows out to the radiator where it's cooled by air flowing over the radiator. From there the coolant/water mix circulates back through the engine to absorb more heat.

There's a reason we mix coolant and water. Water alone actually does a good job transferring heat from the engine. The problem is that water boils at a temperature that's easily reached inside your vehicle's engine, so it can turn to steam which does not conduct heat as well and is harder to contain.

Also, if it's freezing outside in Sierra Vista, the water in your engine could freeze while your vehicle is sitting out in the AZ cold.

So, if you remember your high school chemistry, you'll know that a mixture has both a higher boiling point and a lower freezing point than either component alone.

Coolant, or antifreeze, is specially formulated to keep your engine safe in a wide range of environmental and operating temperatures in and around Sierra Vista.

Whenever your vehicle is running, the coolant in the cooling system is working to keep your engine from overheating. When it's cold outside, the coolant acts as antifreeze to keep the fluid from freezing in your engine.

All that exploding fuel in your engine creates a lot of heat. Without coolant, the metal vehicle engine parts would expand so much that the engine would seize up and stop running. The parts could be broken or warp so badly they would have to be replaced. It could even be so bad that the whole vehicle's engine is ruined and has to be junked.

This is why it is critical that Sierra Vista drivers check coolant levels frequently and have their vehicle's cooling system inspected for leaks. Also your vehicle has a maintenance requirement for draining and replacing your coolant. These recommendations can vary widely, so check your owner's manual or ask us at Arizona Auto and Radiator Repair in Sierra Vista.

The reason Sierra Vista drivers need to change the coolant is that it has additives in it to protect the cooling system. As you can imagine, with all the heat, the cooling system's a pretty harsh environment. The additives keep the fluid from becoming corrosive and damaging the radiator and other vehicle cooling system components. Over time, the additives are depleted and the coolant just has to be replaced.

Many Sierra Vista auto owners ask our advisors at Arizona Auto and Radiator Repair why there are different colors of antifreeze. It is very important that you use the correct type of antifreeze. The different types of antifreeze – or coolant – are different colors so you don't mix them up.

They use different materials to make the cooling system, and they require different types of antifreeze to protect them.

So check with us at Arizona Auto and Radiator Repair in Sierra Vista or your owner's manual for the right kind because using the wrong coolant can void the warranty for your vehicle cooling system.
